As many as 10 of the 17 kinds of penguins（企鵝）may be in danger of disappearing. The number of penguins have decreased(減少) by 30% since 1987.
　　Penguins are black and white birds that live in the southern part of the world. They are common in South America，New Zealand，Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly，but they are fine swimmers. Penguins eat fish and krill(磷蝦).
　　The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖).　 Besides，many adult penguins die of hunger.
　　Widespread(廣泛的) fishing，exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies，including wild dogs，sharks，seals and sea lions.
　　News about penguins is not all bad，however. Several years ago，oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild.　 Now these South African penguins are reproducing in higher numbers than before the oil leaking.
小題1:Penguins ___________.
A．can swim better than flyB．can be found near Oceania (大洋洲)
C．eat fish only冬臘月D．live only in cold waters.
小題2:Which of the following is NOT the cause of penguin's decrease in numbers?
A．Oil searching.B．Widespread fishing.
C．Human's killing.D．Warming of the oceans.
小題3: Why are the penguins in South Africa reproducing in higher numbers than before the oil leaking?
A．Because people removed the ship.
B．Because people sent a lot of penguins to the wild.
C．Because people helped the penguins.
D．Because people treated the penguins well.

小題1:C
小題2:A
小題3:D

Pollution problems are becoming more and more serious. One of them is called “white pollutions” caused by plastic, such as shopping bags, boxes and cups. In China, about three billion plastic shopping bags are used every day, which results in a great waste of resources(資源) and heavy environment pollution. Luckily, the government has stopped us from using free plastic bags, telling all stores and supermarket not to provide customers(顧客) with free plastic bags since June 1,2008. From then on, people have been supposed to use cloth bags and shopping baskets instead of plastic bags in order to protect our environment.
Now, more and more people have realized the importance of using the cloth bags and shopping baskets. For one thing it can protect our environment, for another it can also save energy. Yet we have more things to do to solve the problem of “white pollution”!
小題1:Is “white pollution” caused by plastic?
__________________________________________
小題2:How many plastic shopping bags are used every day in China?

Healthy Food Paris
Spinach + Oranges
Although spinach(菠菜) has lots of iron, your body doesn’t absorb(吸收) it well when spinach is eaten alone.But with vitamin(維生素) C by its side, this vegetable becomes a true hero.

 
Avocado + Tomato
Tomatoes are a super food. Eat some avocado(鱷梨) at the same time and you’ve got a super super food, because the fat in the avocado helps the body absorb seven times more lycopene(番茄紅素).

Drinking several cups of green tea is a good habit, because it can protect your heart. But if you intake some vitamin C at the same time, it can’t be better. The vitamin C in lemons helps your body absorb 13 times more catechins(兒茶酚) than it can get from tea alone.

Not all memories (記憶)are sweet. Some people spend all their lives trying to forget bad experiences. Wars and traffic accidents can leave people with terrible physical and mental scars. Often they appear again in dreams.
Now American researchers think they are close to developing a pill(藥丸), which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce（減少）, or possibly erase(抹去) the effect of sad memories.
In November, some scientists tested a drug(藥) on people in the US and France. The drug stops the body producing chemicals(化學(xué)品) that fix memories in the brain. So far the research has suggested that only the mental effects of memories may be reduced, not that the memories are erased.
The research has caused plenty of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can destroy(破壞) people’s lives. They come back to you when you don’t want to have them in a dream. They usually come with very sad feeling.” said Roger Pitman, a scientist of psychiatry at Harvard Medical School. “This could relieve(減輕) a lot of that suffering.”
But those who are against the research say that it is very dangerous to change memories because memories give us our identity(特質(zhì)). They also help us all get away from the mistakes of the past.
“All of us can think of bad events in our lives that were terrible at the time but make us who we are. I’m not sure we want to erase those memories,” said Rebecca Dresser.
小題1:The passage is mainly about __________.
A．a(chǎn) new medical invention
B．a(chǎn) new research on memories
C．a(chǎn) way of erasing sad memories
D．a(chǎn)n argument about the research on the pill
小題2:The drug tested on people can __________.
A．cause the brain to fix memories
B．stop people remembering their experiences
C．prevent body producing certain chemicals
D．erase the emotional effects of memories
小題3:The word “scars” in Paragraph One is close in meaning to _________.
A．good stories B．sad feelings
C．experiencesD．memories
小題4:Which of the following does Rebecca Dresser agree with?
A．Some memories can destroy people’s lives.
B．People want to get away from bad memories.
C．Experiencing bad events makes us different from others.
D．The pill will reduce people’s sufferings from bad memories.

Mrs Elise was my teacher in the fourth grade. One day at lunch time, I was getting ready to eat my tuna fish (金槍魚(yú)) sandwich and suddenly Mrs Elise asked me if she could buy my sandwich from me. She explained that I could use the money to buy a hot hunch from the cafeteria (食堂).
I was excited. I never bought my lunch at the cafeteria. It was too expensive for my family, and I always carried my lunch and took the bag back home to use it again the next day. So you could understand my happiness when I had the chance to buy a hot lunch.
When we finished lunch that day, Mrs Elise took me aside and said she wanted to explain why she had bought my sandwich. I really didn’t care why, but it gave me a few minutes of her special attention, so I was quiet as she explained. She told me that she was a Catholic(天主教徒) and Catholics didn’t eat red meat on Fridays, they ate fish on Fridays.
Oh, I couldn’t wait to get home and tell my mother that from then on I wanted a tuna fish sandwich on Fridays. After my mother understood why, she gladly made tuna fish sandwiches for me on Fridays. She even made it with brown bread because she knew Mrs Elise liked brown bread. From then on, every Friday I could get in line with other kids for a hot lunch. I didn’t care how many of the kids complained about cafeteria food. It tasted divine to me!
I realize now that Mrs Elise could have made herself tuna fish sandwiches on Fridays. But she bought mine because she saw a little girl who was excited at the simple act of having a hot lunch.
I will never forget Mrs Elise for her pity for me and generosity (慷慨) and what I should do is to follow her example.
